**2. Materials and methods**

The literature review presented below contains a synthesis of the latest studies on the production of vegetable gardens in urban areas, highlighting the production of vegetable gardens in schools. The methods used were studies of free area in school spaces of three schools of early childhood education, investigation of the needs and desires of the school community and researches on types and forms for plant production in urban areas and employability of recyclable materials in its construction. The software Auto Card, a tool for architectural drawings, enabling the creation of gardens for each space studied was used.

For the preparation of the gardens passive recycling materials may be used, through characterization of solid residues, materials that has been discarded by the local population, without appropriate destination for the environment, for example,

Urban agriculture is an activity that has been growing in Brazil and worldwide, according to FAO—Food and Agriculture Organization of the United Nations. This activity refers to the use of surfaces located in urban areas or in their respective peripheries for agricultural production and the creation of small animals intended

Some of the concepts about urban agriculture in general address their relationship with localization. For Dimoud and Nikolopoulou [7], the definition of urban agriculture refers to the location of the spaces within and around cities or urban areas. Therefore, the intra area refers to all spaces within cities that may have some type of agricultural activity, which can be individual or collective, in addition to

Wong [8] stated that the concept of urban agriculture goes beyond what is defined by the area of localization, which is therefore an interaction between the ecological and urban economic system, not being reduced only to the urban

Dimoud and Nikolopoulou [7] stated that this integration is made possible by the fact that urban agriculture has a set of activities (cultivation, breeding, fishing, etc.) that develop in the interior (Intraurban) or in the periphery (periurban) of the

The development of urban or periurban agriculture is directly linked to the demographic and economic growth of cities, contributing to the reconfiguration of urban spaces through land use, population structures, social practices, among other

The advantages of urban agriculture, includes the local development through the rational use of spaces, food security, formation of microclimates, maintenance of biodiversity, water drainage, harvesting of rain water, decreased temperature and income generation. Most common examples of urban agriculture are the community gardens that are most often installed in urban idle areas, which may be public or private, intended for cultivations of vegetables, medicinal plants, legumes, fruits and other foods, providing food for families living near these areas, or seedling

Urban gardens have differentiated configurations, where they almost always

One of the configurations observed in the use of urban gardens is the greenhouses. These are protected agricultural environments where the plastics are used as cladding materials for covering the greenhouse framework, used in the protection of crops, facing the climatic adversities. Agricultural greenhouses are used to create climatic environments suitable for plants, protecting them from poor environmental conditions such as frost, hail, and other weather. They are used for food production, cultivation of ornamental plants, flowers and medicinal plants [10]. Rosenzweig et al. [11] stated that the cultivation in protected environment brings with it numerous advantages such as: harvest in the periods between harvest, faster production cycle due to favorable environment conditions, increase in production, control of the environment promoting the development and production of plants, greater control of pests and diseases that may occur in the protected environment, better use of available resources, reduced risks and increased market

According to Wong [8], besides urban gardens, vertical farms have numerous advantages such as production of several crops throughout the year, zero loss of
